8 HP Briggs and Stratton problems with surging and almost dieing

[Vortec325]

Feels like it has good compression but if I pull it slow I can almost hear some leaking out of the carb .

Ok that's what I needed to know. Let us know what the key looks like.

I pulled the flywheel off and the key looks fine

Finally got a chance to watch your video , your right Bou. The intake valve was fine but the exhaust valve isn't sitting in the seat right, or the seat has worked it's way up . Valve has like .022 of lash

Now it's time to take the head off ~!~!

I've got the head off, looks like the exhaust valve isn't sitting in the seat all the way . Pulled the valve and cleaned the carbon off of it with emery cloth and lapped the valve in . Got the valve lash better but still looks like the exhaust valve isn't seating right

Is the seat in the block all the way ??

 

[Vortec325]

Looks like it , sitting about the same as the intake valve seat . I tried wiggling it around and it isn't loose . I'll take a picture for yah here in a minute
